Which company owns MAC address prefix C4:50:9C?

MAC address prefix C4:50:9C is registered to Vantiva - Connected Home in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with C4:50:9C has a network interface built by Vantiva - Connected Home.

What is the OUI C4:50:9C?

C4:50:9C is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to Vantiva - Connected Home. It covers every address from C4:50:9C:00:00:00 to C4:50:9C:FF:FF:FF, or 16,777,216 addresses in total. It is also written C4-50-9C.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in C4:50:9C:00:00:00 that is C4:50:9C — and look that prefix up in the IEEE OUI registry. If the second-lowest bit of the first octet is set, the address is locally administered (a randomized or private MAC), which belongs to no manufacturer and will not resolve; modern phones and laptops use these by default on each network.

Where is Vantiva - Connected Home located?

Vantiva - Connected Home is listed at 4855 Peachtree Industrial Blvd, #200 Norcross GA US 30092 in the IEEE OUI registry entry for C4:50:9C. This is the address the organization registered with the IEEE, which may differ from its current operating address.
